Hi Guys just a little update. i started playing with pjsip 1.8 an SDK 4.1 and seems like the EC is not working :-(, i can hear my voice pretty much intact coming back from the iPad. do you think this would be different if i use and iPhone ? any suggestion how to get the EC on manually. or maybe us portaudio and the speex echo canceller instead of the core audio? thanks On Aug 23, 2010, at 10:27 PM, Sauw Ming wrote: > Hi Rob, > > Glad that you finally solved the problem.
